What are the members of the subphylum Vertebrata?

1: Diversity of vertebrates: animals with backbones: The subphylum Vertebrata contains all animals that possess backbones, gills, and a central nervous system in at least one phase of development. Vertebrates include amphibians, reptiles, mammals, and birds, as well as the jawless fishes, bony fishes, sharks, and rays.

What are the divisions of Vertebrata?

Let's take a tour of the five main vertebrate groups alive today: the fishes, amphibians, reptiles, birds, and mammals.

What is the difference between Chordata and Vertebrata?

Chordates are characterized by the presence of a notochord. ... The main difference between chordates and vertebrates is that some chordates do not have a vertebral column whereas all vertebrates have a vertebral column. In vertebrates, the vertebral column surrounds and protects the nerve cord.

How many classes are under the phylum Chordata?

The phylum chordata (animals with backbones) is divided into five common classes: fish, amphibians, reptiles, mammals and birds. Show examples of these groups and explain the characteristics that make one different from another.

What are the 5 classes of subphylum Vertebrata?

Vertebrate Classification. Vertebrates can be subdivided into five major groups: fishes, amphibians, reptiles, birds, and mammals. Amphibians, reptiles, birds, and mammals are ranked as classes.

Is Vertebrata a class?

Vertebrata - Vertebrates

Vertebrates also have a well-developed brain, a pair of eyes, a circulatory system with a heart, a pharynx, and a mouth with muscles! Humans, birds, mammals, reptiles, amphibians, and fish are all vertebrates. There are seven living classes of vertebrates.

What are the two super classes of phylum vertebrata?

Gnathostomata has two super classes, Pisces and Tetrapoda. Classes Chondrichthyes and Osteichthyes bear fins for locomotion and are grouped under Pisces.

What is the major subphylum in phylum vertebrata?

The group Vertebrata is currently placed as a subphylum in the phylum Chordata, together with two other subphyla, Cephalochordata (lancelets) and Urochordata (ascidians).

What is the meaning of subphylum Vertebrata?

Medical Definition of Vertebrata

: a subphylum of chordates comprising animals (as mammals, birds, reptiles, amphibians, and fishes) with a segmented spinal column together with a few primitive forms in which the backbone is represented by a notochord.

How many classes are in phylum?

Unsourced material may be challenged and removed. The following is a list of the classes in each phylum of the kingdom Animalia. There are 107 classes of animals in 33 phyla in this list. However, different sources give different numbers of classes and phyla.

What does the subphylum Vertebrata have that Cephalochordata do not have?

The lancelets are also called cephalochordates (Greek: kephale, “head”) because the notochord extends from near the tip of the tail to well into the anterior of the body. Because they do not have the braincase, or cranium, of a vertebrate, lancelets are often called acraniates.

What is difference between notochord and vertebral column?

The key difference between notochord and vertebral column is that notochord is a flexible rod-like structure that supports the nervous tissue in lower chordates, while the vertebral column is a structure containing 33 vertebrae, running from the skull up to the pelvis in vertebrate higher chordate animals.
